This study investigated the effect of two concentrations of H2S on the atmospheric corrosion of pure Ag, Cu, and Ni. The corrosion products were analyzed using various techniques such as SEM/EDX, Raman spectroscopy, XPS, and XRD. Different corrosion products were identified based on the characterization methods, providing a better understanding of the impact of H2S on the atmospheric corrosion of these metals. The possible mechanisms involved in the formation of these corrosion products were also discussed in this study.
The effect of two concentrations of H2S (0.5 and 2.5 ppm), in controlled laboratory conditions (20 degrees C, 75%RH), on the atmospheric corrosion of pure Ag, Cu and Ni was investigated in this study. The corrosion product morphology and composition were analysed through a multi-technique approach including SEM/EDX, Raman spectroscopy, XPS and XRD. Different corrosion products were identified depending on the type of character-isations providing a better overview of the effect of H2S on the atmospheric corrosion of pure Ag, Cu and Ni. Possible mechanisms involved in the formation of these corrosion products are also discussed in this work.
